GAS HEATING-STOVE.

Specification of Letters Patent.

Patented Apr. 2"?, 1915.

Application filed October 23, 1912. Serial No. 727,421.

T0 all whom t may concern:

Be it known that I, MINARD A.. PossoNs, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful improvements in Gas Heating- Stoves, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in gas heating stoves, and pertains to a stove which involves a combined reflector and drum heater.

The object of my invention is to provide a combined reflector and drum heater of an improved construction, whereby an increase in the reflector and drum heating capacities is accomplished.

A. further obj ect of my invention is to pro vide a gas heater having a combined heating reflector and heating drum, the reflector being semicircular in cross-section with an enlarged bottom tapered upwardly to a reduced upper portion, and a semicircular heating drum surrounding the upper reduced end of the reflector and projecting therefroml with its periphery substantially in the vertical plane of the lower enlarged semicircular portion of the reflector, an air circulating passage behind the reflector and adapted to take cold air from the bottom of the reflector at the floor of the room and pass it behind the reflector to be heated and through the open upper end of the passage, thus providing increased heating surface and a circulation of the air in the room, which adds to the heating elliciency of the stove.

In the accompanying drawings-Figure 1 is a front elevation of my improved gas heater. Fig. 2 is a cross-sectional view on the line 2-2, looking in the direction indicated by arrows. Fig. 3 is a cross-sectional view on the line 3 3 of Fig. l, looking in the direction indicated by arrows. Fig. 4 is a vertical central longitudinal sectional view on the line 4-4 of Fig. 1. Fig. 5 is an enlarged detached perspective view of the semi-circular burner tube and its attached supply tube and gas controlling valves.

Referring now to the drawings, 1 indicates a semicircular base, which is provided with the supporting feet 2, that support the drum a suitable distance above the floor upon which it is to be placed. This drum l has an open lower end 3 and an open top 4f. Supported upon the top of this semicircular drum l is a reflector 5, which has its lower and enlarged end 6, semicircular in shape to correspond with the semicircular shape of the top 4 of the drum 1. is shown, the lower enlarged semicircular end 6 of the drum 5, incloses the open top 4l of the drum or base 1. This reflector 5 tapers from the enlarged end 6 upward to its reduced end 7, the reflector being however substantially semicircular in cross-section at all points throughout its height from the enlarged lower end 6 to its reduced upper end 7. As here shown, this reflector is provided with a series of longitudinal ribs 8, which project radially from the outer surface of the reflector forming the spaces 9 therebetween, these spaces contracting from their lower ends upward.

Located above the upper end of the reflector 5 is a heating drum 10. This heating drum is semicircular in cross-section and of a cross-sectional area corresponding with that of the base or drum 1. The lower end 11 of this heating drum 10 extends slightly below the upper end of the rellector 5 and incloses it. This drum is of a height substantially equal to the height of the reflector 5, thus constituting what might be termed a vertically elongated drum having a radiating surface of suflicient area to best and mostl efliciently receive the radiated heat from the reflector and to utilize it for heating purposes.

. The semicircular wall 12 lits the upper end 7 of the reflector 5 and extends upward through the heating drum 10 and fits a correspondingly shaped outlet opening 13, in the top 14C of the drum 10, thus forming a vertical passage l5 through the heating drum 10.

The back of the heater consists of a vertical wall 16, which together with the reflector 5 forms a vertically arranged passage 17, which has its lower end communicating with the drum 1, and its upper end communicating with the passage 15, thus constituting a continuous passage from the floor of the room through the base 1 behind the reflector 5, and through the heating drum 10 to cause a circulation of the cold air from the drum 10, and has outwardly extending vertical flanges 18. Attention is directed to p the fact that the reflector 5 has laterally eX- tending portions 5 at each side of the semi- 5 circular portion of the reflector and that these lateral extensions 5 of the reflector eX- tend from the bottom to the top of the reflector and out to the edges of the wall 16, which, together with the semicircular portion of the reflector makes the reflector coextensive with the widthor diameter ofthe drums 1 and 10. The rear wall of the passage is formed'by a plate 19, located apart from the wall 16, which forms a space 15 20 between the-passage 15 and the wall 16, and this passage is in communication with the interior of the drum 10 at its ends 21.

, Communication. between the passage 15 and Y the interior of the heating drum 10 is estab' lished by a Ysuitable number of openings 22 formed in the `semicircular wall 12. A semicircular defiector plate 23 extends outward from the semicircular wall 12 and has its edge apart from the wall of the heating drum 10 to form a passage 24 between the outer edge of the deflector plate 23 rand the wall of the heating drum.` This passage 24 places the interior of the heating drum in communication with-the space 25 above the reflector 5, and between it and the lower edge of the heating drum 10. The wall of the heating drum 10 has a series of openings 26 arranged aroundv the heating drum inV substantially the same horizontal 36 plane as the deflector 23, ,which establishes communication between the interior of the drum and the surrounding atmosphere at this point.

A flanged flue opening 27 is formed in the back wall 16 in communication with the passage 2O so that the interior of the heat ing drum may be placed in communication with a flue if desired. A suitable cap l28 is shown for closing the flanged opening 27,

when it is not in communication with a ue.

Located between` the upper end of the reflector 5 and the defiector 23 is aburner tube 29 of semicircular shape, as clearly shown in Figs. 2 and 5, so that the burner tube is l shaped to correspond with the semicircular contour of the upper end of the reflector and is preferably placed adjacent to but apart from both the reflector 5 and the Ydeflector 23, which forms a semicircular space 30 be- 65 :tween the burner tube and the deflector, and

also a space 31 between the upper side of the Vvburner tube and the deflector 23. This curved burner tube 29 has its closed end suitably supported by a bracket 32 and its open end in communication with a supply tube 33, the lower end of which is provided with a bracket 34 that is bolted at the point 35 tothe wall or backing 16. By means of vthese brackets 33 and 34 the burner and its connected supply tube are supported. A

supplynozzle 36 is connected with Athe gasV receiving end of the pipe 33 and thisV nozzle is provided with a suitable controlling valve 37. Located at the junction of thepipe 33 and the nozzle 36 is a regulating valve 38 70 adapted to be adjustedby a screwdriver for regulating the pressure flow to the burner I tube 29, and this regulating valve is preferably provided with a removable protecting cover or cap 39. By means of this pres- V sure regulating valve, the flow of the gas can be controlled to the burner according to the gas pressure, instead of requiring a separate adjustment of the valve 37 for that purpose each time the stove is lighted. Y

The above mentioned semicircular burner tube 29 is provided with a series ofl radially projecting burner passages 40 located on the outer curved side of the tube, as clearly shown. A Y 1 A castingv 41 having aplurality of upwardly curved arms 42 is secured overY the upper end'of the Ypassage 15, for; the pur-V pose of protecting the passage and it will y serve as a handle by which the stove may be lifted from `olace to place. p. i Y

In operationthe burner flames proj ect'foutl Y: ward fromfthe burner tube 29 under the deiiectorplate23, and a current of heat passes A Y therefrom againstv the deflector and around-Y` 9'5 betweenitsouter edge and the wall of the heating drumlO. Radiated heat is reiiected V from the semicircular reflector 5in a radial direction forming a semicircularheat radiatedV space, and heat is also radiated or reflected from the portions y5 Vof thereflector. By reason of the semi-circular shape of the reflector and the heating drum and, infact, the complete stove, `the heat is thrown therea from in a semicircular radiated direction, so I that several persons may be seated around the front of the stove and have the benefit of the reflected e and radiated heat. This shape, therefore, radiates or reflects the heat.

in front and in all-'radial directions there- 1110Y around, thus adding to the area orY radius of the heat capacity of the stove,ras com'- pared with other forms of this type ofthe Y stove known to me. This isequally true,v of the semicircular heating :drum-10.V In addition to the'lateral heat radiation and reflection the top of the drum radiates the heat upward, and a circulation of airis caused in the room by the passage of cold airH from the bottom ofthe baseil of the stove upward behind the reflector andV through the passage 15, which is inclosed within the' heating drum and out through the top Y.opening 13, thus adding additional heating efficiency as well as a circulation of the air in the room `to be heated c s l A suitable brace 41 yextends across the base 1, between its front edge and the backing 16. `For appearance, and possible utility, a semicircular rail 42r extends around in 130 front of the stove just above the lower end of the reflector 5 and is provided with an intermediate standard 4:3. This rail may be used as a foot support if desired.

The eficiency of the reflector is increased by reason of the corrugations 44, and the vertically arranged ribs 8, forming the vertical passages between them, as above explained.

Having thus described my invention, what l claim and desire to secure by Letters Patent is:

l. A gas heating stove comprising a base, substantially semicircular in cross section, a vertically arranged `heat reflector having an enlarged lower end at the top of the base, the reflector tapered upwardly to a reduced upper end, a heating drum above the reflector, and substantially semicircular in cross section and overhanging the upper end of the heat reflector, an outwardly extending deflector plate at the lowerend of the heating drum and the upper edge of the reflector, and the wall of the heating drum and the outer edge of the deflector plate separated to form a passage, the lower edge of the heating drum having a plurality of openings therearound in substantially the same horizontal plane as that of the deflector plate and a burner tube curved around the upper portion of the reiector and provided Gopes of this patent may be obtained for with a plurality of radially arranged burner openings.

2. A gas heating stove comprising a base, a rear vertically disposed wall carried by the base, a heating drum supported by the vertically disposed wall and of a cross sectional area substantially corresponding with that of the base, a heat reflector located between the base and the drum and spaced from the rear vertical wall, a vertically disposed flue in communication with the space between the reflector and rear vertical wall and passing through the heating drum and spaced from the walls thereof, an outwardly extending deflector plate adjacent the lower end of the heating drum and the upper edge of the reflector, and having its outer edge spaced from the drum, the lower edge of the heating drum having a plurality of openings in horizontal alinement with the deflector plate, and a burner around the upper portion of the deflector plate and provided with a plurality of radially arranged burner openings.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
